Allow propagation of errors and retry through StreamDataProvider

StreamDataProvider::provideStreamData now has a rich enough API for it
to effectively proxy to pipeStreamData.

-* (Source compatibility) As somewhat discussed in issue 219, the
-  original pipeStreamData in QPDF_Stream has various logic for
-  reporting warnings and letting the caller retry. This logic is not
-  implemented for stream data providers. When copying foreign streams,
-  qpdf uses a stream data provider (QPDF::CopiedStreamDataProvider) to
-  read the stream data from the original file. While a warning is
-  issued for that case, there is no way to actually propagate failure
-  information back through because
-  StreamDataProvider::provideStreamData doesn't take the
-  suppress_warnings or will_retry options, and adding them would break
-  source compatibility.
